
For the two modules that
communicate with each other, the
serial port baud rate can be
different, and the verification
method can also be different.

When transmitting large packets
continuously, users need to
consider the data blocking caused
by the same baud rate, and data
may even be lost. It is generally
recommended that both parties
have the same baud rate.
-------------------------------------

It should be the same for both
communication parities .

The higher the rate, the shorter the
distance.


When the data is smaller than the
sub packet length, the serial output
of the receiving end is an
uninterrupted continuous output.
When the data is larger than the
sub packet length, the receiving
end serial port will output the sub
packet.


When enabled, the C0 C1 C2 C3
command can be sent in the
transmitting mode or WOR
transmitting mode to read the
register.
Register 0x00: Current ambient
noise rssi
Register 0X01: rssi when the data
was received last time.
（
Current channel noise is: dBm
=-RSSI/2
）
Command format: C0 C1 C2 C3 +
starting a read length
Returns: C1 + address a read
read valid value
E.g: send C0 C1 C2 C3 00 01
Return C1 00 01 rssi
